It's the beep beep beep that Lando does with his watch thingy to Lobot. It's the same beep beep beep as Luke's on Hoth. Plus, Lando's beep is not in sync with his finger movement.
Like I said, just a small thing!
Just a small thing, but how cool a fix would that be?! It's something I've always noticed, too. Well, not so much the actual sound, but the sync.
